11 1. Safety Information 1.0 Safety Information The following warnings and safety instructions apply to all sections of these Operating Instructions. Parts may fly off during operation. Keep a safe distance away from the machine! 1.1 Safety Symbols on the machine Read and observe the Operating Instructions before using the machine! Keep clear of the working range of foldable machine components! Watch out for escaping pressurised fluids! Follow the instructions in the Operating Instructions! No passengers are allowed on the machine! Never reach into areas where there is a danger of being crushed by moving parts! Never reach into any revolving parts! Centurion CDA600 9

12 1. Safety Information Refer to Operating Instructions before attempting maintenance. Operating Instructions: The Operating Instructions distinguish between three different types of warning and safety instructions. The following graphic symbols are used: Important! Risk of injury! Risk of fatal and serious injuries! It is important that all the safety instructions contained in these Operating Instructions and all the warning signs on the machine are read carefully. Ensure that the warning signs are legible. Replace any signs that are missing or damaged. These instructions must be followed in order to prevent accidents. Inform other users of the warnings and safety instructions. Do not carry out any operations which may affect safe use of the machine. All references to left and right in this manual are made from the rear of the machine, facing the direction of travel (unless otherwise stated). 10 Centurion CDA600

13 1. Safety Information 1.2 Use for the Intended Purpose The Centurion is built using the latest technology and in accordance with the relevant recognised safety regulations. However, risks of injury for the operator or third parties and impairment of the machine or other tangible assets can arise during use. The machine is only to be operated when in a technically perfect condition and for the intended purpose, taking into consideration safety and risks and following the Operating Instructions. In particular, faults that can impair safety are to be remedied immediately. Original parts and accessories from Great Plains have been specially designed for this machine. Spare parts and accessories not supplied by us have not been tested or authorised. Installation or use of nonoriginal Great Plains products may have a detrimental effect on specific design features of the machine and affect the safety of machine operators and the machine itself. Great Plains will accept no liability for damage resulting from the use of non-original parts or accessories. 1.3 Operational Safety The machine is to be put in operation only after instruction has been provided by an employee of the authorised dealer or an employee of Great Plains. The Machine Registration form is to be completed and returned to your dealer. All protective and safety equipment, such as removable protective equipment, must be in place and functioning reliably before the machine is put in use. Check screws and bolts regularly for tightness and retighten if necessary. In the event of malfunctions, stop and secure the machine immediately. Ensure that any faults are remedied immediately. The Centurion is designed solely as a cultivation and seeding implement. Use for any other purpose, e.g., as a means of transport, will be deemed to be improper use. Great Plains will accept no liability for damage resulting from improper use. The risk will be borne solely by the operator. Use of the Centurion behind high power tractors (in excess of 40% above the maximum recommended) can lead to high loads and stresses which can cause long term structural damage to the chassis and key components. Such overloading can compromise safety and is to be avoided. Centurion CDA600 11

14 1. Safety Information 1.4 No Liability for Consequential Damage The Centurion has been manufactured with great care. However, problems may still occur when it is used for the intended purpose. These may include: Worn wearing parts. Damage caused by external factors. Incorrect driving speeds. Incorrect setting of the unit (incorrect attachment, non-adherence to the Setting instructions). Therefore, it is crucial to always check your machine before and during operation for correct operation and adequate application accuracy. Compensation claims for damage which has not occurred to the machine is excluded. This includes any consequential damage resulting from incorrect operation. 1.5 Hitching-up the machine 1.6 Hydraulic System Do not connect the hydraulic lines to the tractor until both hydraulic systems (machine and tractor) are depressurised. Any hydraulic system containing an accumulator can remain under pressure permanently (even after following manual depressurisation procedures with a tractor / implement combination). It is therefore important to check all lines, pipes, and screw connections regularly for leaks and any recognisable external damage. The hydraulic circuit contains specialised fittings which should not be tampered with under any circumstances. Do not attempt to modify hose routings or hose clamping arrangements, doing so my cause serious damage to the machine and/or injury. There is a risk of injury when hitching/ unhitching the machine. Observe the following: Secure the machine against rolling. Take special care when reversing the tractor! There is a risk of being crushed between the machine and the tractor! Park the machine on firm, level ground. Figure 1. HydraulicTaps The socket and plugs for the hydraulic connections between the tractor and the machine should be colour-coded in order to avoid incorrect use. Avoid High Pressure Fluids - Escaping fluid under pressure can penetrate the skin, causing serious injury. Avoid the hazard by relieving pressure before disconnecting hydraulic lines. 12 Centurion CDA600

15 1. Safety Information Use a piece of paper or cardboard, NOT BODY PARTS, to check for suspected leaks. Wear protective gloves and safety glasses or goggles when working with hydraulic systems. If an accident occurs, seek immediate medical assistance from a physician familiar with this type of injury. 1.7 Changing Equipment / Settings Secure the machine to prevent it from accidentally rolling away! Use suitable supports to secure any raised frame sections suspended above you! Caution! Risk of injury due to projecting parts! Never climb on to rotating parts such as the roll unit. These parts may rotate causing you to slip and suffer serious injury! Removing components during maintenance may affect the stability of the machine. Ensure it is fully supported in case of unexpected weight shifts. 1.8 During Operation Ensure that the working range and the area around the machine are clear (children!) before operating the machine. Always ensure adequate visibility! Do not stand on the machine while it is in operation! Operators must have a valid driving licence in order to drive on public roads. In the operating area, the operator is responsible for third parties. The person in charge must: provide the operator with a copy of the Operating Instructions, and ensure that the operator has read and understood the instructions. make sure that the operator is aware of the specific regulations relating to the machine when driving on public roads. Beware of trapping hazards when manipulating moving parts (changing tine depth for example). Ensure any heavy components are fully supported when removing pins / bolts. Centurion CDA600 13

16 1. Safety Information 1.9 Servicing & Maintenance Ensure that regular checks and inspections are always carried out within the periods required by law or specified in these Operating Instructions. When carrying out service and maintenance work always: switch off the tractor engine and remove the ignition key. wait until all the machine parts have stopped moving. depressurise the hydraulic system. Many hydraulic circuits contain lock or overcentre valves which can retain pressure in the lines even after depressurising the tractor side of these circuits. If in doubt, consult trained personnel (such as your local Great Plains Dealer) to ensure such valves are depressurised to the correct procedure before removing or servicing any parts connected downstream of these valves. Check all hydraulic lines for leaks, loose connections, chafe marks and damage. Remedy any deficiencies immediately! Pay particular attention to hose renewal intervals as outlined in the specific sections which follow. ALL hydraulic hoses have a safe maximum working life of 6 (SIX) years from date of installation, provided they remain in a safe condition. Hoses which exceed 6 years of age should be replaced, or inspected and certified by a suitably qualified person to have an extended life period which should be recorded. Pay particular attention to those items which require specialist service tools or training to be carried out by qualified personnel. Do not attempt to service these items yourself! These include items retaining pressure (e.g. hydraulic circuits), or force (e.g. spring tines / levelling boards). Prior to performing maintenance and servicing work, ensure that the machine is positioned on solid, level ground and is secured to prevent it rolling away. Do not use any parts to climb on to the machine unless they are specifically designed for this purpose. Before cleaning the machine with water, steam jets (high-pressure cleaning apparatus) or other cleaning agents, cover all openings into which, for reasons of safety or operation, no water, steam or cleaning agents are to penetrate (bearings, for instance). Lubricate all the lubricating points to force out any trapped water. When carrying out servicing and maintenance work, retighten any loose screw connections. When servicing the machine take precautions against soil, dust, seed coatings, oil or any other hazardous substances that you might encounter. On a new machine tighten all nuts and bolts after 5 hours work and again after 15 hours. This also applies to parts that have been moved or replaced. After the initial 15 hours of work a once a week check should be sufficient depending on daily work rates. 14 Centurion CDA600

17 1. Safety Information 1.10 Operating Areas The operating areas include the drawbar, hydraulic connections, cultivation section, hopper, seed coluters, markers as well as all operating points requiring maintenance. All operating areas will be specified and described in detail in the following chapters on servicing and maintenance. Observe all safety regulations included in the section dealing with Safety, and in the subsequent sections Authorised Operators Only those persons who have been authorised and instructed by the operator may operate the machine.

Centurion CDA600 15

18 1. Safety Information 1.14 Chemical Safety 1.15 Hopper Safety A hopper that is full or merely appears full can be an entrapment hazard. You can sink entirely into the material, or into an oxygendeficient void, and suffocate in a matter of seconds. Bridges and crusts are especially dangerous. Agricultural chemicals can be dangerous. Improper use can seriously injure persons, animals, plants, soil and property. Do not enter a hopper for material loading, material unloading, hopper cleaning or meter maintenance. Do not use liquid seed treatments with the Centurion Drill. Read and follow chemical manufacturer s instructions. Wear protective clothing / gloves when handling chemicals. Perform meter maintenance by removing meters from bottom of empty hopper. Only use the steps / walkways on the machine for hopper filling, do not climb on any other parts of the machine. 16 Centurion CDA600

19 1. Safety Information 1.16 Tyre Safety Tyre changing can be dangerous and should be performed by trained personnel using correct tools and equipment. When inflating tyres, use a clip-on chuck and extension hose long enough for you to stand to one side not in front of or over tyre assembly. Use a safety cage if available. When removing and installing wheels, use wheel-handling equipment adequate for weight involved Safety Lights and Devices Slow-moving tractors and towed implements can create a hazard when driven on public roads. They are difficult to see, especially at night. Use flashing warning lights and turn signals whenever driving on public roads. Use lights and devices provided with implement Road Traffic Safety When driving on public roads, tracks and areas, it is important to observe the relevant local road traffic laws as well as the specific regulations relating to this machine. Pay attention to the permitted axle loads, tyre carrying capacity, and total weight in order to maintain adequate braking and steerability. Keep clear of overhead power lines and other obstructions when transporting. Refer to transport dimensions under Technical Data on page 33. Do not fold or unfold the drill while the tractor is moving Transport Checklist Plan the route. Keep clearances in mind. Folded, the Centurion drill is 3.22m high (with markers fitted) and is 3m wide. Ensure hydraulic, electrical and braking connections are secure. Close and secure hopper cover. Check that boutmarkers are stowed. If unfolded, fold and lock. See Folding on page 27. With tractor in Park, remove the wheel chocks.

21 2. Transportation / Installation 2.0 Transportation and Installation Transportation and initial installation of the machine are described in this chapter. 2.1 Delivery The machine is normally delivered fully assembled. The machine should be hitched to a tractor and driven off a low-loader. 2.2 Transportation The Centurion can be transported on public roads by hitching it up to a tractor or on a low-loader. It is important to observe the permitted dimensions and weights when transporting the machine. If the machine is transported on a trailer or a low-loader, it must be secured using straps or other devices. 2.3 Installation When carrying out installation and maintenance work there is a higher risk of injury. It is important that you familiarise yourself with the machine and read the Operating Instructions beforehand. Operator instruction and initial installation of the machine are carried out by our service technicians or authorised distributors. The machine must not be used in any way beforehand! The machine can only be released for operation after instructions have been provided by our service technicians or authorised distributors. If any modules or parts have been removed for transportation, these shall be mounted by our service technicians/ authorised dealers before the instruction takes place. Check all important screw connections! Lubricate all nipples and joints! Check all hydraulic connections and lines for damage. Before transporting the machine on public roads, it must be adjusted to its transportation position and the stipulations relating to road transportation fulfilled. The maximum permissible speed is 30kph (20mph). The hopper should be emptied before road transport. Do not attempt to move or transport the machine in the maintenance position (with the lock channels removed). Centurion CDA600 19

22 2. Transportation / Installation 2.4 Preparation and Setup This section helps you prepare your tractor and Centurion for use, and covers seasonal tasks, and tasks when the tractor/ drill configuration changes. Before using the Centurion in the field, you must hitch the drill to a suitable tractor, inspect systems and level the drill. Before using the drill for the first time, and periodically thereafter, certain adjustments and calibrations are required Initial Setup Install the monitor console in the tractor cab. Mount the console so that it is easy to monitor during planting, but does not interfere with safe operation of the tractor in the field or on public roads Pre-Planting Setup Complete this checklist before routine setup: Read and understand Safety Information section starting on page 9. Check that all working parts are moving freely, bolts are tight, and cotter pins are spread. Check that all grease fittings are in place and lubricated. See Maintenance and Lubrication on page 72. Check that all safety decals and reflectors are correctly located and legible. Replace if damaged. Inflate tyres to pressure recommended and tighten wheel bolts as specified. See Tyre Inflation Chart on page 80. Set boutmarker extension (page 38) Seasonal Setup On initial delivery, use with a new tractor, and seasonally, check and as necessary, complete these items before continuing to the routine setup items: Wing levelling and alignment. Speed sensor calibration. Blow out entire air system to remove condensation. Check air flow at each row, for evidence of plugging. De-grease exposed cylinder rods if so protected at last storage. 20 Centurion CDA600

23 2. Transportation / Installation 2.5 Hitching Tractor to Drill You may be severely injured or killed by being crushed between the tractor and drill. Do not stand or place any part of your body between drill and moving tractor. Stop tractor engine and set tractor parking brake before attaching cables and hoses. 1. Back up the tractor to align tractor link arms and drill linkage. 2. Engage the link arms and the drill linkage, ensuring the balls are seated correctly. 3. Raise the link arms / linkage and move the parking stand into the work position. 4. Shut down tractor and remove key. 5. Connect hydraulic hoses (page 22). 6. Connect brake hoses (page 23). 7. Connect electrical cables (page 24). Centurion CDA600 21

24 2. Transportation / Installation 2.6 Hydraulic Hose Hookup Escaping fluid under pressure can have sufficient pressure to penetrate the skin causing serious injury. Avoid the hazard by relieving pressure before disconnecting hydraulic lines. Use a piece of paper or cardboard, NOT BODY PARTS, to check for leaks. Wear protective gloves and safety glasses or goggles when working with hydraulic systems. If an accident occurs, seek immediate medical assistance from a physician familiar with this type of injury. Only trained personnel should work on system hydraulics! Great Plains hydraulic hoses are colour coded to help you hook-up hoses to your tractor outlets. Hoses that go to the same remote valve have the same colour handles. The fan pressure hose (black) must be connected to a circuit capable of continuous flow at high volume. To distinguish hoses on the same hydraulic circuit, refer to labels at the hose ends. Low Pressure (Case) Drain Connection: Attach case drain hose to low pressure drain connection in order to protect fan hydraulic motor seals. For the hydraulic fan, connect the hose with a retracted cylinder symbol to the pressure side of the motor. The fan motor further requires hook-up of a (third) case drain line, which returns lubricating/cooling fluid. 2.7 Brake Hook-up Two braking (trailer braking) systems are available for the Centurion; a dual-line air system, and single-line hydraulic system. In both systems, the tractor s trailer brake remote port(s) operate a hydraulic slave cylinder on the drill. Tractor trailer braking systems are normally integrated with the tractor brakes, and operate the trailer brakes when tractor brakes are used during tractor movement.the trailer braking system may or may not be integrated with the tractor parking brake system. Trailer brakes typically are not automatically engaged when the tractor transmission is in Park, and may not be engaged by any tractor Emergency Brake. Make sure the operator understands when drill brakes are engaged and when they are released. Also understand and comply with tractor operational restrictions when trailer brakes are used. For example, it is generally necessary to inter-tie split brakes, and avoid differential (steering braking) if trailer brakes are used. Connect low pressure motor return hose, marked SUMP, to a high volume low pressure return port. The sump line is distinguished by a ¾in BSP connector. 22 Centurion CDA600

25 2. Transportation / Installation Air Brake Hook-up Please refer to the following procedure when coupling or decoupling any item of Great Plains machinery fitted with an AIR brake or AIR and HYDRAULIC brake system. Please note that this procedure does not apply to any machines fitted with a HYDRAULIC system ONLY. When Coupling: 1. Reverse up to the machine and connect the machine to the tractor as instructed to on page With the machine connected couple the air lines. When coupling ensure the yellow line is attached first followed by the red line. 3. Your brake hoses are now attached and are ready for operation. 4. Continue with the coupling process as instructed on page 21. By following these instructions you will see that at NO point in the coupling or decoupling process has the red line been left in the tractor on its own. This is intentional and should be considered the rule to coupling the hoses. Do not use the Centurion with a single-line air brake system. This drill is designed for transport speeds that require an air brake system to be dual-line. A singleline tractor system cannot charge the tank that powers the drill brakes Hydraulic Brake Hook-up This is a single hydraulic line, connected to the tractor Brake outlet. This has a female connector. When De-coupling: 1. Bring the machine to the parking position as instructed to on page With the machine still connected to the tractor remove the red brake line followed by the yellow line. 3. Your brakes will now be ON and will hold, ensuring they have been adjusted and maintained correctly, the machine in position. (note: if the machine s tank is drained of air once all lines have been detached the brakes will come off (same situation as pushing the shunt valve). Figure 2. Brake connection hose. 4. Continue de-coupling the machine until it is fully disconnected. Centurion CDA600 23

26 2. Transportation / Installation Hydraulic Colour Coding The hydraulic Hoses are colour coded using cable ties to identify the different circuits. Hoses with 1 tie indicates the cylinder side of the circuit while hoses with 2 ties indicate the rod side. P1 P2 Levelling board 1 Levelling board 2 Memory 1 Memory 2 Fan Sump Drain Electrical Hook-up Make sure tractor is shut down with accessory power off before making connections. 1. Mate lighting connector to tractor outlet. 2. Mate monitor connector to tractor harness. 3. Mate any optional or after-market electrical connectors. Make connections prior to drill movement. Some drill hydraulic circuits are under monitor control. Figure 3. Electrical Connectors Beacon Operation The flash strobe beacon should be on in all instances when the machine is being transported or used. It is part of the main light circuit and is on when the lights are on Stow Wheel Chocks Verify that the tractor transmission is in Park, and that the tractor s parking brake is set. Two sets of wheel chocks (4 chocks total) are provided to secure the drill when parked. These provide the safety when installed ahead and behind the transport tyres. If one chock is extremely difficult to remove, and/or the drill moves significantly when the chock is removed, investigate the cause before removing the chocks on the other side. If no tractor is hitched, or the tractor is not securely parked, the drill could roll away after chock removal, and cause an accident resulting in death, serious injury and substantial property damage. 24 Centurion CDA600

27 2. Transportation / Installation 2.8 Heights and Levelling All frame sections must be at the correct height and level to maintain even planting depth. The hitch height sets the mainframe level, and must be at a consistent height to both maintain level, and maintain radar speed calibration. Periodic frame-levelling adjustments should not be necessary. If you are having problems with uneven depth, level drill if necessary. To ensure consistent seeding depth the frame should be set level while planting. Failure to do so may result in implement not producing desired results. 3. Lower and unfold the implement (page 26). 4. Pull forward 10 metres or so to put openers in the ground. 5. Check toolbar height across drill Boutmarker Setup Prior to first use the marker extension should be set or reviewed. See Boutmarker Adjustments on page 38. Prior to each planting session, check and adjust Boutmarker Disc Adjustment on page Checking Drill Height The implement frame should be level with the ground during planting, this will allow the row units to operate at their most consistent planting depth. Your crop, soil conditions, disc wear and other factors may create a need to use a different toolbar height. Cultivation disc and levelling board height is controlled hydraulically ahead of the tyre packer. On machines fitted with the weigh cell option, wing weight transfer is controlled automatically. The pressure can be monitored using the upper gauge at the front of the machine. When checking toolbar height: 1. Move the drill to representative planting soil conditions. 2. Set linkage height.

28 2. Transportation / Installation 2.10 Unfolding and Folding Unfold and fold implement only if fold hydraulics are bled free of air and fully charged with hydraulic oil. Keep away and keep others away when unfolding or folding. Keep clear of overhead power lines when unfolding, operating, folding or transporting the drill. Machine is not earthed. At higher voltages, electrocution can occur without direct contact. Any line voltage present on implement, cart or tractor can cause severe injury or death. Keep people away from the drill and tractor during folding. Risks include pinching or crushing at pivot points and at multiple sites in pivoting assemblies. Ensure that wing lock is engaged correctly. If a hydraulic failure occurs, or hydraulic levers are moved, unlocked wings could fall suddenly causing a major road accident, or crushing anything near the wings, resulting in death or serious injury, and property damage. Do not use tyres as steps or platforms. All tyres can be in light ground contact, or free to spin, when implement is lowered. Fold only on hard level ground. if parked across a slope, wing lock bars could be difficult or impossible to engage or release. When folding and unfolding, the working elements of the drill (eradictors, cultivation discs, levelling boards and row units) should be raised to avoid damage Unfolding These steps presume a drill folded for transport, such as at initial delivery. Follow the detailed instructions below until this is a familiar operation. 1. Move the drill to level ground with adequate overhead and lateral clearances for the fold operation. 2. Ensure that the working elements are raised. Unlock the taps and lower the drill (activate circuit using raise/lower button). 3. Disengage the wing lock. Figure 4. Wing Lock 4. Press the Fold key on the control panel to select the fold circuit. The tractor spools can then be used to fold / unfold the wings. One wing may reach the ground before the other. It is not uncommon for the folding to be slightly non-symmetrical. 26 Centurion CDA600

29 2. Transportation / Installation Folding Fold the drill for moves between fields, transport over public roads, parking and storage. Follow the detailed instructions below until this is a familiar operation. 1. Make sure boutmarkers are fully folded. 2. Move the drill to level ground with adequate overhead and lateral clearances for the fold operation. 3. Ensure that the working elements are raised. 4. Activate the fold circuit on the control panel to retract the fold cylinders. One wing may reach the stop before the other. A slight asymmetry is not uncommon in folding. 5. Ensure that the wing lock engages correctly. 6. Activate the lift circuit using the 'road transport button on' the lift circuit. Retract the lift cylinders to raise drill to the lock channels. Lock using taps. Ensure the hopper side panels are closed before folding the machine. Centurion CDA600 27

30 2. Transportation / Installation 2.11 Lowering and Raising Drill This section refers to the lowering and raising of the entire drill using the lift axle cylinders. Stay clear of wings and openers during lowering and raising. Wings are extremely heavy and are driven down with hydraulic pressure. Disc blades and opener discs are sharp. During lowering, openers will cut or crush anything beneath them, and can cause serious injury or death. The centre section is held up only by hydraulic pressure, and may slowly lower over time. It may lower more rapidly if the hydraulic system is damaged. They lower rapidly if the hydraulics fail, or the Lift circuit is set to Float Lowering Check that maintenance lock channels are installed on wheel lift cylinders. The drill should be lowered before folding and unfolding (ensure that the working elements are still raised). Make sure all persons are clear of opener sections. The drill is lowered by selecting the 'road transport' button on the control panel and operating the tractor spool. Do not stand on tyres. Wheels may turn suddenly and without warning if used as a step, resulting in serious injury. Set tractor brakes / use Park to avoid tractor movement. Remain clear of all tyres and row units during raise and lower. Do not lower while any folding or unfolding operations are under way or partially complete. Openers can dig in or drag on ground and be damaged. 28 Centurion CDA600

31 2. Transportation / Installation Raising The working elements should be raised for folding and unfolding. If lowered, the working elements on the inside of the wings drag or dig sideways during fold/unfold, and damage is likely. Always fully raise the cultivation section / row units for tight turns and reverse/backing operations. Backing with openers lowered may cause damage to openers. Tight turns with openers lowered may damage openers near the turn centre. Verify that all persons are safely clear of implement sections. After folding the machine, press the 'road transport' button on the control panel. This will activate the circuit allowing the machine to be raised / lowered on the transport wheels using the tractor spools. The cylinders can then be locked using the taps (see Figure 6). The cylinders should be retracted to the lock channels for road transport before locking with taps. Figure 6. Lock channel in work / transport position. The lock channels are used to restrict cylinder stroke during normal operation. The lock channels should ONLY be moved out of the way to allow the machine to be fully raised for maintenance. Do not attempt to move the machine while it is in the maintenance position. Figure 5. Lock channel in maintenance position Centurion CDA600 29

32 2. Transportation / Installation 2.12 Transporting the Drill Tractor must weigh at least 67% of the drill as towed. Ensure that the towing vehicle is adequate for the task. Using an inadequate tow vehicle is extremely unsafe, and can result in loss of control, serious injury and death. See table on opposite page. Do not tow if drill exceeds the load rating of the vehicle. Check bridge loads and plan routes accordingly. A loaded drill can exceed the load ratings of bridges you must cross. Maximum transport speed is 30 kph (20 mph) at all times, and lower with a lighter tractor. Excess speed can result in loss of control or inability to stop. Reduce speeds with materials loaded, or if road conditions are less than ideal. Inflate tyres to factory specifications. Tighten wheel nuts to specifications. Underinflated tyres or loose nuts can cause loss of control. Overinflated tyres or over-tightened nuts can fail suddenly and cause loss of control. Loss of control can cause a major accident resulting in death, injury and equipment damage. Check lights and reflectors regularly. Replace bulbs and faded/worn/missing decals as required. Use lights in transport. These features are critical to visibility, particularly with other drivers unfamiliar with farm equipment or not expecting to encounter a slow-moving vehicle. Front lights should be moved into the road transport position. Ensure the wing lock is engaged when the wings are folded. Figure 7. Front lights in road transport position 30 Centurion CDA600

33 2. Transportation / Installation 2.13 Parking the machine In order to avoid damage as a result of moisture, the machine should be parked, if possible, indoors or under cover. When manoeuvring the machine, pay attention to your surroundings. Ensure that nobody is in the manoeuvring area (watch for children!). 1. Park the machine on level and solid ground. 2. Lower the machine onto the parking stand / transport wheels ensuring that it is stable. Ensure pin is fitted correctly. 3. Place wheel chocks under wheels. 4. Uncouple the machine from the tractor link arms. 5. Switch off the tractor and remove key. 6. Uncouple the hydraulic hoses and electrical / brake connectors. Figure 8.

Great Plains Centurion Front Linkage Track Eradicators Cultivation Discs Levelling Board Tyre Packer Disc Coulters Pre-Emergence Marker Following Harrow Seed Towers Boutmarker Hopper 34 Centurion CDA600 Designed to set new standards in productivity, efficiency and operating economy, the Centurion incorporates a host of innovative features alongside proven technologies. The result is a disc-based cultivator drill, ideally suited to min-till and plough-based establishment systems, that delivers superb drilling accuracy, consistent seed placement and reliable depth control across a wide range of soil types and conditions. The Centurion is born out of the time proven Great Plains 'Science of Seeding' philosophy that provides uniform emergence and optimum yield.

37 4. Adjustment / Operation 4.2 Operating Instructions This section covers general operating procedures. Experience, machine familiarity, and the following information will lead to efficient operation and good working habits. Always operate farm machinery with safety in mind. To get full performance from your Centurion, you need an understanding of all component operations, and many provide adjustments for optimal field results. Even if your planting conditions rarely change, some of these items need periodic adjustment due to normal wear. 4.3 Pre-Start Checklist Perform the following steps before transporting the Centurion drill to the field. Check all hydraulic lines and fittings before applying pressure. Escaping fluid under pressure can have sufficient pressure to penetrate the skin. Fluid escaping from a very small hole can be almost invisible. Use paper or cardboard, not body parts, and wear heavy gloves to check for suspected leaks. If an accident occurs, seek immediate medical assistance from a physician familiar with this type of injury. Review Safety Information section starting on page 9. Lubricate as indicated at Maintenance and Lubrication on page 72. Check all tyres for proper inflation. See Tyre Inflation Chart on page 80. Check all bolts, pins, and fasteners. Torque as shown in Torque Values Chart on page 80. Check drill for worn or damaged parts. Repair or replace parts before going to the field. Check hydraulic hoses, fittings, and cylinders for leaks. Repair or replace before going to the field. Centurion CDA600 35

38 4. Adjustment / Operation 4.4 Tongue The Centurion is fitted with a Category 3 or 4 cross-shaft linkage at the front of the machine. 4.5 Track Eradictors The track eradicators are mounted on a hydraulically controlled beam allowing them to be moved to follow the tractor wheels. Each tine is sprung, allowing it to 'trip' over any stones or other obstructions in work to avoid damage. The depth of the track eradicators can be adjusted by removing the pin and moving the notched profile up or down in the mounting bracket before refitting the pin. Figure 10. Drawbar w/cross-shaft linkage Figure 11. Track eradicators in raised position Figure 12. Track eradicators in work position 36 Centurion CDA600

39 4. Adjustment / Operation 4.6 Cultivation Section The Centurion features two rows of cultivation discs which chop and mix the crop residue. A disc spacing of 250mm ensures a fine tilth. The 460mm notched cultivation discs feature maintenance-free sealed hubs and rubber mounts to provide shock absorption. Soil deflectors are mounted at the end of the wings to hold soil within the machine width. The Centurion has a fully adjustable progressive entry/exit lift sequence for discs & levelling board/coulters and a 'half-lift' function for faster headland turns (with operator-set limits for disc/levelling board/coulter lift height). Independent 'onthe-move' height adjustment of cultivating discs/levelling board is also possible. Cultivation section depth settings are controlled using memory cylinders. These hydraulic cylinders work by shortening the cylinder stroke to achieve the cultivation depth the user requires. Figure 13. Levelling Board Angle Adjustment. Centurion CDA600 37

40 4. Adjustment / Operation 4.7 Boutmarkers Marker Extension Adjustment At delivery, marker extension is typically set for shipment (arm fully retracted), and needs to be reset for field. Marker extension needs to be checked periodically thereafter, and needs to be checked and adjusted when: machine depth is changed, marker disc angle is changed, or; marker disc throw direction is changed. To change marker extension, on a lowered drill: 1. Pull forward approximately 10m to leave a mark and a furrow. 2. Loosen the U bolt (A) securing the outer marker arm. 3. Slide the outer arm in or out until the disc is at the desired extension distance. 4. Re-secure the U bolt. 5. Fold the marker. 6. Boutmarker discs may be sharp. Use caution when making adjustments in this area. Figure 14. Boutmarker Measure marker extension in representative field conditions, with openers in ground, after adjusting cultivation section height (page 37) and wing weight transfer (if applicable). If openers are not at planting depth when setting extension, the bout gap will be too large during planting. A Figure 15. Boutmarker adjustment Marker extension is measured on the ground, from the centre-line of the outside row unit to the disc mark. The marker extension is simply one half the span (distance between end rows) plus a bout gap of one row space. 38 Centurion CDA600

41 4. Adjustment / Operation Boutmarker Disc Adjustment The boutmarker disc angle can be changed using the adjuster at the end of the extension arm. By loosening bolts A and B the disc can pivot to the desired angle before retightening. Mark visibility may be enhanced by inverting the disc on the disc axle. Remove the outer axle nuts. Invert the disc and re-secure with nuts. Check marker extension after adjusting. These adjustments may cause minor or major changes to marker extension, which could result in incorrect gaps between bouts, or overlaps. A B Figure 16. Boutmarker disc angle adjustment Centurion CDA600 39

42 4. Adjustment / Operation 4.8 Hopper Hopper capacity is 4,100 litres, which feeds a 125mm diameter metering roller with unique flute design to eliminate 'seed pulsing'. Everything from oilseed rape to beans can be delivered in rates from 0.5kg 500kg/ha with just three manuallyinterchangeable rollers. Figure 17. Hopper The hopper is fitted with a front window and 3 hopper level sensors are installed, with only two being active at any one time. This allows the top two to be manually plugged in /unplugged according to the size of the seeds being drilled. The hopper features an opening of 2.7m long x 1m wide - ideal for bucket loading. It also has a shut off flap for easy metering roller change Loading Hopper Entrapment and Rapid Suffocation Hazard: Never enter a hopper for loading, unloading or routine maintenance. Keep cover closed during operations. Keep cover locked closed during storage. Keep children away from drill. 40 Centurion CDA600 A hopper that is full, or merely appears full, can be an entrapment hazard. You can sink entirely into the grain, or into an oxygen-deficient void, and suffocate in a matter of seconds. Grain bridges and crusts are especially dangerous. When hazardous fumes or low oxygen levels are present, you can be quickly overcome even in an empty hopper with the cover open. There may be no odours to alert you to the hazard. Turn off fan before opening hopper covers. Wear eye protection and dust mask or respirator. Even with the fan off, adding seed or fertilizer will create a dust cloud. Risks include exposure to hazardous chemicals, lung and eye irritation Hopper Cover Operation Keep hopper cover closed. Open only for material loading, hopper clean-out and exceptional maintenance. Wear gloves suitable for protection against recent fertilizers or seed treatments. The hopper cover is opened and closed by winding the handle.

43 4. Adjustment / Operation 4.9 Fan General Information The hydraulic fan supplies the air stream that carries materials from the meters, through the primary hoses to the towers, then to the secondary hoses to the rows. The fan needs to be running in the correct direction, and within a narrow speed range, to reliably deliver material at your calibrated rates. Machine Damage Risk: Always engage the fan with the tractor at a low engine speed. Engaging the fan when the tractor is at high speed may cause fan damage. Do not reverse hydraulic flow with the fan running Fan Field Operation With the tractor engine at low rpm, slowly Extend the lever for the Fan circuit. Bring the fan up to recommended speed (page 42). Let the fan warm up for 15 minutes before planting. Lower the drill 1.5-3m (5 to 10ft) before planting is to begin. It takes a few seconds for seed to travel from the meters to the rows Fan Speed The specific fan rpm required varies considerably with drill configuration, material density, application rate, field speed and material properties. Develop and record settings that are suitable for your operations. Always engage the fan with the tractor at a low engine speed. Engaging the fan when the tractor is at high speed may cause fan damage. Do not reverse hydraulic flow with the fan running. At ideal fan speed: flow is more than high enough to avoid blockages (from both meters on dualhopper drills), flow is even across all hoses from each meter; and, flow is low enough to minimize seed cracking and bounce. Fan speed is monitored and reported by the seed monitor, but is manually controlled. If the fan cannot reach 3000 rpm, one or more hoses may be mis-connected. Air moves toward the air box in either rotation direction, but reverse spinning airflow is too low to operate the system. Leave the fan running during field turns. Meter drive is shut off when the openers are raised. At the end of application, raise openers. Stop material flow before shutting off the fan. Shut off the fan by carefully moving the Fan circuit lever to Float. The fan does not stop instantly. A check valve in the fan circuit locally re-circulates oil until the blades coast to a stop. Centurion CDA600 41

44 4. Adjustment / Operation Adjusting Fan Speed The fan speed should be adjusted according to your situation. Start with flow on low setting litres/ min Source: M (8-12 gpm) is average flow. Provider: Dated: TJP T00:00 Run the fan for at least 15 minutes before seeding.

Field mode ensures all tires stay in contact with ground for headland turns. Transport mode increases ground clearance. To put the machine in maintenance mode the lock channels should be removed to allow the cylinder to retract fully (see page 29). Fan RPM Limits Minimum Maximum 2000 rpm to 4500 rpm Typical Range Minimum Maximum Milo 3250 rpm to 4000 rpm Soybeans 2750 rpm to 3500 rpm Sunflower 2250 rpm to 3000 rpm Wheat 3250 rpm to 4000 rpm Figure 18.

45 4. Adjustment / Operation 4.11 Seeding Elements The Centurion has precise injection molded seed distribution heads with built-in tramline shut offs and optional seed flow sensors accurately deliver seed to each coulter. Accurate Seed Placement is handled by heavy duty coulter arms with kg adjustable down-pressure and easy depth adjustment. There is an option of 167mm or 125mm coulter spacing. The Centurion's acclaimed drilling coulter features a pair of robust 4mm discs staggered front/back by 8mm so they open an effective seed slot. Discs are mounted on heavy-duty arms that can apply up to 210kgs down pressure which ensures penetration in the hardest conditions Row Unit Adjustments The Great Plains 00 Series row unit can include the following capabilities (some optional): 1. Down Pressure Spring - Each row unit is mounted on the implement via arms which allow the row unit to independently move up and down. The adjustable spring sets the force at which the opener rides up over obstructions. See Row Unit Spring Adjustment on opposite page. 2. Disc Blades - Double disc blades open a furrow, creating the seed bed. Spacers adjust the blades for a clean furrow. See Disc Blade Adjustments on page Seed delivery tube - This tube delivers material from the hopper. No adjustments are necessary. 4. Press wheels - These close the seed trench. The press wheels also support the free end of the row unit, and provide the primary control over seeding depth via the T-handle. See Opener Depth (Press Wheel Height) on page Seed firmer - seed flap (not shown) A seed flap requires no adjustment, other than replacement when worn. Keeton seed firmer (shown) Improves seed-soil contact, and provides a stable arm for a low-rate liquid fertilizer delivery tube. See Keeton Seed Firmer Adjustment on page Inside Scraper - Helps prevent clogging between disc blades. See Opener Disc Scraper Adjustments on page 45. Figure 19. Row Unit 7. Following Harrow - Levels the ground after seeding. Centurion CDA600 43

46 4. Adjustment / Operation Row Unit Spring Adjustment Row unit springs normally require no adjustment. The factory setting for the row unit springs is: Spring length mm Assembly length mm In some unusual conditions, rows in tyre tracks may need to be set heavier. Make adjustments with the wings unfolded and the rows lifted off the ground, so that the springs are at full extension Opener Disc Adjustments Opener disc angle and stagger is not adjustable, but disc-to-disc spacing is, and may need attention as discs experience normal wear. Spacers will need to be reset when blades are replaced. The ideal spacing causes the blades to be in contact for about 25 mm. If you insert two pieces of paper between the blades, the gap between them should be 0 to 44 mm. If the contact region is significantly larger or smaller (or there is no contact at all), it needs to be adjusted by moving one or more spacer washers. If the contact region varies with blade rotation, one or both blades is likely bent and in need of replacement. Figure 20. Row Unit Spring Loosen the locking nut. Rotate the adjuster nut. Shorten spring to increase down-force; lengthen spring to reduce down-force. For each turn of the adjuster nut, the down force at the opener disc changes by approximately 1.7 kg/turn. Figure 21. Checking Disc Contact Re-tighten locking nut after setting force. 44 Centurion CDA600

47 4. Adjustment / Operation Adjusting Disc Contact Use caution when making adjustments in this area. Row unit disc blades may be sharp. Unfold implement. Configure implement for maintenance lift lock (page 29). Remove the bolt retaining the opener disc on one side. Carefully remove the blade, noting how many spacers are outside the disc and how many are inside the disc. Do not lose the hub components and spacers. To reduce the spacing between the discs (the normal case), move one spacer washer from the inside to the outside. When installing new blades, it is generally necessary to move outside spacers back inside after both discs are mounted Opener Disc Scraper Adjustments Slotted disc scrapers are standard. Springloaded carbide disc scrapers are optional. To keep opener discs turning freely, dirt scrapers are mounted between discs to clean as discs rotate. Use caution when making adjustments in this area. Row unit disc blades may be sharp. As field conditions vary, scrapers may need to be adjusted. In damp conditions, lower scrapers. If openers are not turning freely, raise scrapers. To adjust, loosen bolt and move scraper as needed. Re-assemble and check disc contact. Figure 23. Scraper Adjustment Figure 22. Adjusting Disc Spacers Centurion CDA600 45

48 4. Adjustment / Operation Seed Firmer Adjustments Row units include a seed flap, and accept one of two optional seed firmers. The seed flap requires no adjustment, but may need to be replaced if worn, and may need to be shortened if an optional seed firmer is added after initial delivery. Row unit disc blades may be sharp. Use caution when making adjustments in this area. To adjust the Keeton Seed Firmer, lower the drill until the discs of the row units are resting on the ground Keeton Seed Firmer Adjustment The optional Keeton Seed Firmer is an engineered polymer shape that slides down the seed trench. It traps seeds as they exit the seed tube and firms them into the bottom of the V. The firmer is provided with a preset tension which is recommended for using the first year. The tension screw can be tightened in subsequent years according to your needs. Firmers should provide just enough tension to push seeds to the bottom of the trench Opener Depth (Press Wheel Height) Refer to Figure 25. Set opener seeding depth by adjusting press-wheel height. To adjust, first raise openers slightly, then lift and slide T handles on top of openers. Adjust all press wheels to the same height. Each increment of the handle adjusts the seeding depth by approximately 6mm. The range is approximately 0-89 mm seeding depth. For more shallow seeding, slide T handles forward toward implement. For deeper seeding, slide T handles backward away from implement. If moving the T handle backward doesn t cause the opener to achieve desired depth, lower the disc coulters by lowering the frame height, and increase weight transfer pressures if necessary. Figure 25. Adjusting Opener Depth Figure 24. Keeton Seed Firmer 46 Centurion CDA600

49 4. Adjustment / Operation Row Unit Down Pressure 4.13 Pre-Emergence Markers The down pressure of the row units is controlled using the knob and lower gauge at the front of the drill (A and B on Figure 26). The pre-emergence markers work after the seeding elements. They are able to be repositioned laterally on the beam in order to provide the best fit for tractor / sprayer wheelings. Always run openers level in work. The depth can be adjusted using pins at the top end of the marker arm. Disc angles can be adjusted by loosening the bolt and repositioning the angled blocks (Figure 29). A B Figure 26. Row Unit Pressure Adjustment 4.12 Following Harrow Adjustment Figure 28. Pre-emergence Markers The following harrow can be adjusted by loosening the bolts (1 in Figure 27) and repositioning as required (in most instances the arm should be set close to horizontal). After repositioning ensure all bolts (including bolt 2) are retightened. Figure 29. Disc Adjustment Figure 27. Following Harrow Adjustment Centurion CDA600 47

50 4. Adjustment / Operation 4.14 Work Instructions Driving speed In work the Centurion can be driven at speeds of up to 12 km/h. This depends on the field conditions (type of soil, surface trash, etc.). Drive more slowly if the conditions are difficult or a firmer finish is required Turning Before turning in work, at headlands for instance, all the ground engaging elements (cultivation section / row units) should be lifted out of work while driving, allowing the machine to turn on the packer wheels. These elements should only be lowered back into work once the turn has been completed. Depending which work mode is set on the control panel, the elements will either lift and lower in sequence or lift together and lower in sequence Checks The working quality depends on the adjustments and checks made prior to and during work, as well as on regular servicing and maintenance of the machine. Before beginning work it is therefore important to carry out any necessary servicing and to lubricate the machine as required. Checks prior to, and during work: Is the machine correctly hitched up and the coupling device locked? Is the machine in a level operating position and the working depth set correctly? Working Elements Are the discs and other cultivation tools in a serviceable condition? Are the scrapers still operable, so that the coulters do not jam? Wing Pressure Wing down pressure is controlled automatically. The pressure is shown on the upper gauge at the front of the drill. 48 Centurion CDA600

72 5. Servicing and Maintenance 5.0 Servicing and Maintenance Follow the safety instructions for servicing and maintenance. 5.1 Servicing Your machine has been designed and constructed for maximum performance, operational efficiency and operator friendliness under a wide variety of operating conditions. Prior to delivery, your machine has been checked at the factory and by your authorised dealer to ensure that you receive a machine in optimum condition. Adjustments may be needed to suit your field conditions. 5.3 Preparation for Storage If you need to store the machine for a longer period, observe the following points: Park the machine undercover if possible. Protect the discs against rust. If you need to spray the implements with oil, use light, biologically degradable oils, e.g. rape oil. Cover any rubber sections before using oil sprays. These sections must not be oiled. Remove any traces of oil with a suitable cleaning agent. To ensure trouble-free operation, it is important that servicing and maintenance work is performed at the recommended intervals. 5.2 Cleaning In order to ensure that the machine is always in operating condition and to achieve optimum performance, perform the cleaning and servicing work at regular intervals. Avoid cleaning any bearings with a highpressure hose or a direct water jet. The housing, screwed connections and ball bearings are not watertight. Do not apply wax to any steps or platforms. This may cause people to slip and fall causing injury. 70 Centurion CDA600

73 5. Servicing and Maintenance 5.4 Cultivation Elements When performing maintenance work on cultivation elements (discs, levelling boards, eradictor tines) extreme care should be taken. Wear goggles and gloves at at all times when maintaining ground engaging parts. Do not attempt to assist fitting working elements with a steel headed hammer, this can lead to splintering of the metal due to its hardness, which can cause injury. If fitting requires assistance, a copper/hide or plastic mallet should be used. Safely support unfolded machine in raised position using taps and stands before attempting maintenance work on elements under the machine. 5.5 Operator Support If you have a problem, please contact your dealer. They will endeavour to solve any problems which may occur and provide you with support at all times. In order to enable your dealer to deal with problems as quickly as possible, it helps if you can provide them with the following data. Always state the: 5.6 Maintenance Intervals Apart from daily maintenance, the maintenance intervals are based on the number of operating hours and time data. Keep a record of your operating hours to ensure that the specified maintenance intervals are adhered to as closely as possible. Never use a machine that is due for maintenance. Ensure that all deficiencies found during regular checks are remedied immediately. Avoid sharp-edged and pointed parts (disc blades, etc.) when working on the machine. Place the machine on suitable supports when working underneath! Do not work under a machine which is not supported! On a new machine tighten all nuts and bolts after 5 hours work and again after 15 hours. This also applies to parts that have been moved or replaced. After the initial 15 hours of work a once a week check should be sufficient depending on daily work rates.

74 5. Servicing and Maintenance 5.7 Maintenance and Lubrication Proper servicing and maintenance is the key to long implement life. With careful and systematic inspection, you can avoid costly maintenance, downtime and repair. Always turn off and remove the tractor key before making any adjustments or performing any maintenance. You may be severely injured or killed by being crushed under a falling implement. Always use suitable supports when working near or under a raised implement. Escaping fluid under pressure can have sufficient pressure to penetrate the skin. Check all hydraulic lines and fittings before applying pressure. Fluid escaping from a very small hole can be almost invisible. Use paper or cardboard, not body parts, and wear heavy gloves to check for suspected leaks. If injured, seek immediate medical attention from a health care provider familiar with this type of injury. Securely lock up drill before working on it. Lubricate areas listed under Maintenance Overview on page 74. Check for air leaks at covers, doors, seals, caps and hose connections. Inflate tyres as specified on Tyre Inflation Chart on page 80. Replace any worn, damaged or illegible safety decals. Order new decals from your Great Plains dealer. 5.8 Handling of Lubricants Please ensure that you read the following instructions as well as the relevant information. This also applies to any of your employees who handle lubricants. Hygiene Lubricants do not present a health hazard provided they are used for their specified purpose. In the case of prolonged skin contact, lubricants - especially low-viscosity oils - may remove the natural layer of fat contained in the skin, resulting in dryness and possible irritation. It is important to take extreme care when handling waste oil as it may contain other irritants. Vapours given off by cleaning agents and oils are also a potential health hazard. You should therefore not carry any oily cloths around. Change soiled work clothing as soon as possible. Always exercise extreme care and observe the recommended hygiene rules when handling mineral oil products. Details of these handling regulations can be found in information provided by the health authorities. Storage and Handling Always store lubricants where they cannot be accessed by children. Never store lubricants in open or unlabelled containers. Fresh Oil Apart from taking the usual care and observing hygiene rules, there is no need to take any special precautions when handling fresh oil. 72 Centurion CDA600

75 5. Servicing and Maintenance Waste Oil Waste oil can contain harmful contaminants which may cause skin cancer, allergies and other illnesses. Attention! Oil is a toxic substance. Should you swallow any oil, do not try to vomit. Contact a doctor immediately. Protect your hands with barrier cream or wear gloves to avoid contact with the skin. Wash off any traces of oil thoroughly with soap and hot water. Wash your skin thoroughly with soap and water. Use special cleaning agents to clean any dirt off your hands. Never wash oil residue from your skin with petrol, diesel fuel or paraffin. Avoid skin contact with any oily clothing. Do not keep any oily rags in your pockets. Wash soiled clothing before wearing it again. Ensure that any oily footwear is disposed of in the proper manner. Measures in case of injury through oil Eyes: Should any oil be splashed into your eyes, rinse with water for 15 minutes. If the eye is still irritated, contact a doctor immediately Oil Spills Use either sand or a suitable granular absorbent to soak up any spilt oil. Dispose of the oil-contaminated absorbent in the proper manner. Oil Fires Never use water to extinguish an oil fire. The oil will float on the water causing the fire to spread. Burning oil-lubricant must be extinguished using a carbon dioxide powder or foam extinguisher. Always wear respiratory equipment when dealing with fires of this type. Waste Oil Disposal Oil-contaminated waste and used oil must be disposed of in accordance with current legislation. Waste oil must be collected and disposed of in accordance with local regulations. Never pour used oil into unsealed sewage systems or drains or onto the ground. 5.9 Lubricants All lubricating points on the machine can be lubricated with multigrade lubricating grease as specified in DIN KP/2K If oil is swallowed If oil is swallowed, it is important not to induce vomiting. Contact a doctor immediately. Skin irritation caused by oil In case of prolonged skin contact, wash off the oil with soap and water. Centurion CDA600 73
